citra-qt: Remove disassembler widget

It has performance problems, a very misleading UI, and is broken in
general. It has essentially been superceded by the GDB stub, but if we
wanted a built-in disassembler in the future it'd essentially need to be
rewritten from scratch anyway.

Closes #427, #1480
